[PATCH v4 0/3] Make test selection easier by specifying description substrings instead of just numeric counters

This patch series enables me to change

 ./t9999-my-test.sh --run=1-3,5,17,19

into

 ./t9999-my-test.sh --run=setup,rename,symlink

and have it pick out tests with "setup", "rename", or "symlink" in their description and run those. Saves me a lot of time, especially since numbers for tests aren't readily accessible. The easiest way for me to get the numbers corresponding to the tests I want to run, is to run all the tests and look at the output to match up the descriptions with their numbers -- thus defeating the point of selecting just a subset of the tests to run in the first place.

Changes since v3:

 * Added text to the README explaining what to do if the substring you want
   to search on includes a comma or whitespace (namely, use the '?' glob
   character instead)

Elijah Newren (3):
  test-lib: allow selecting tests by substring/glob with --run
  t6006, t6012: adjust tests to use 'setup' instead of synonyms
  test-lib: reduce verbosity of skipped tests

Range-diff vs v3:

 1:  9c8b6a1a94 ! 1:  8f5d4ad318 test-lib: allow selecting tests by substring/glob with --run
     @@ t/README: For an individual test suite --run could be used to specify that
      +numbers separated with a dash and matches a range of tests with both
      +ends been included.  You may omit the first or the second number to
      +mean "from the first test" or "up to the very last test" respectively.
     ++
     ++The argument to --run is split on commas and whitespace into separate
     ++strings, numbers, and ranges, and picks all tests that match any of
     ++the individual selection criteria.  If the substring of the
     ++description text that you want to match includes a comma or space, use
     ++the glob character '?' instead.  For example --run='unnecessary?update
     ++timing' would match on all tests that match either the glob
     ++*unnecessary?update* or the glob *timing*.
       
       If --run starts with an unprefixed number or range the initial
       set of tests to run is empty. If the first item starts with '!'
